Sink bowl



March 3, 1953 R. HARTOG SINK BOWL Filed May 10, 1949 ROBBERT HARTOG Patented Mar. 3, 1953 UNITED STATES PATENT QEEEQE Application Maylfl, 1949, SerialNo. 92 ,379 In Canada Septemberl fi, 134 8 3 Claims.

This invention relates to sink bowls, and more particularly to means for installing sink bowls in drain boards. The methods which heretofore have been employed for the installation of sink bowls inthe standard types of drain boards, involving; such operaticns as, recessing the edges of the, drain board providingfrnoulding to. conceal the edges of the bowl, have had the common disadvantages of requiring time-consuming and expensive hand-fitting and extensive operations for se uring the. sink bowls, to the drain boards. main object of this invention is to. overcome the disadvantages. of the prior. art by providing a sink bowl so constructed that it may be installed quickly and easily with a minimum of hand-work.

A further object of this invention is to provide a sink bowl which may be conveniently installed in a standard type or drain board so as to produce a permanently tight and sanitary seal between the edges of the bowl and the drain board.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in conjunction with the accompanying drawings, wherein like characters of reference indicate corresponding parts throughout the several views and wherein:

Fig. 1 is a side elevation of the sink bowl prior to installation in a drain board;

Fig. 2 is a top plan view of the sink bowl in-,

stalled in a drain board; and

Fig. is a section on the line 3-3 in Fig. 2.

The illustrated construction includes a bowl l9 having an outwardly extending horizontal top rim ii and a central depressed portion or sump l2 surrounding aperture l3 which is provided for connection to a suitable drain pipe. The bowl ill is shown as being generally square in shape and having four substantially flat sides is joined by rounded corners, but any suitable shape may be used.

Suitably spaced around the sides of the bowl it are the vertical supporting strips 55, which are welded or otherwise secured to the bowl so as to extend downwardly from the flange H to apoint somewhat below the underside of the bowl it. The end portions 56 of the strip l5 are not secured to the sides of the bowl it and before the installation of the bowl are left extending vertically downward. A hole I? is provided in each of the end portions is of the strip.

The drain board E8 in which the sink bowl is to be installed is formed with an aperture the dimensions of which may vary between thelimits o1 theinnerand outer dimensions of'theflan'ge H. The drain board It ispre ferably'provided with afprotective covering [9, consistingof'lijnoleum or cther hard, impervious material, oifit may be wholly made from suchmaterial V The sink bowl ill is installed in a drain board {8 by placing the bowl in the aperturefin; the drain board so that the flange H engages with the drain" board and supports the sink bowl 'lll in'the aperture. The run H is preferably. formed with aslight taper towards the outer edgefas shown, so as tov form substantially'af continuation ofthe surface of the protective covering I9.

Threaded rods or bolts 263 each preferably having a flat head 2! and having a threaded portion 22 are then inserted in the holes ll in the unsecured end portions N5 of the supporting strips it, the nut 23 being first threaded on the rod or bolt 2% to provide with the operative part of the threaded rod or bolt an expansible clamping member. The unsecured end portion it of the strip is is then bent upwardly and outwardly to an approximately horizontal position so that head 2! of the bolt Zil is located directly below the drain board I8. By tightening the nut 23 downward on the threaded portion 22 of the bolt to the clamping member provided between the end portion l5 and the drain board I8 by the operative parts of the nut and bolt is expanded to force the head 2i upward against the underside of the drain board, thereby tightly clamping the top rim ll against the upper surface of the protective covering it, and fixedly securing the sink bowl ill in position.

It will be seen that no recessing operation, which would destroy the impervious nature of the protective covering is, is required and a tight seal between the flange and the protective covering i9 is easily provided. Furthermore, the aperture in the drain board need not be cut so as to provide an accurate fit with the bowl i0, thereby effecting a further saving in the time required for installation.

It is thought that the construction and use of the invention will be apparent from the above description of the various parts and their purpose. It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to, without departing from the spirit of the invention or the scope of the subjoined claims.

What I claim as my invention is:

1. Means for mounting a sink bowl within an aperture in a drain board, said means comprising the combination of a sink bowl having an outwardly extending top rim adapted to overlie the edges of the said aperture, supporting vertical strips on the bowl and having bendable unsecured end portions, the said end portions extending outwardly from the sides of the bowl and below the level of the underside of the drainboard after insertion of the bowl in said aperture, and upwardly and downwardly expansible threaded clamping means adapted to engage and bear downwardly against the unsecured bent end portions at points spaced from the bowl and expansible to bear upwardly against the underside of the drain board rigidly to secure the bowl in the drain board.

2. Means for mounting a sink bowl within an aperture in a drain board, said means comprising the combination of a sink bowl having an outwardly extending top rim adapted to overlie the edges of the said aperture, supporting vertical strips on the bowl and having bendable unsecured end portions, the said end portions having apertures and being adapted to be bent outwardly from the sides of the bowl after insertion of the bowl in said aperture, and extensible means adapted to extend through and engage the unsecured bent end portions and to bear against the underside of the drain board rigidly to secure the bowl in the drain board.

3. Means for mounting a sink bowl within an aperture in a drain board, said means comprising the combination of a sink bowl having an outwardly extending top rim adapted to overlie the edges of the said aperture, supporting vertical strips secured to the bowl and having bendable unsecured end portions, the said end portions being adapted to be bent outwardly from the sides of the bowl after insertion of the bowl in said aperture, and threaded rods adapted to the bent unsecured end portions, the said rods carrying nuts adapted to be screwed downwardly toward the bent unsecured end portions, thereby causing the ends of the rods to move upwardly and bear against the underside of the drain board rigidly to secure the bowl in the drain board.
